Methods and systems for detecting staple cartridge misfire or failure

摘要

Systems and methods are provided for detecting misfire of a surgical staple cartridge and for indicating such misfire to a user on a user interface. An actuation force applied to a staple cartridge is measured and compared to a threshold actuation force. In response to the comparison, a controller determines if there has been a misfire of the surgical staple cartridge. A determination that misfire has occurred is made when the measured actuation force is greater than a maximum threshold force or less than a minimum threshold force, and under such circumstances, the controller terminates the staple firing sequence.

主权项

1. A method of controlling a surgical stapler system, the method comprising:
monitoring a drive parameter of an actuator operatively coupled to transmit an actuation force to jaws of a surgical stapler end effector, the jaws being configured to move toward one another over a clamping range of motion to perform a clamping procedure, wherein the monitoring occurs while the actuator is transmitting the actuation force to move the jaws over at least part of the clamping range of motion; comparing the monitored drive parameter to a preset threshold value; and controlling a continued transmission of the actuation force based on the comparison.
